摘要

In this paper, the economic model predictive control operation of a home microgrid with photovoltaic-combined heat and power storage systems is investigated. The purpose of the paper is to present the problem formulation, and quantify the impact of uncertainty coming from the thermal behavior of the mini combined heat and power plant. A model predictive control-based strategy is contrasted with an open loop-based operation and a perfect forecast based operation. The paper discusses the effects of having such an uncertainty, relaying the benefits of using model predictive control to handle such situations. Additionally, the paper at hand presents a sensitivity analysis regarding storage size, concluding that the proposed economic model predictive control strategy can be used to reduce total annual costs.
